Objective This study evaluated the quality and reliability of unassessed DDH health information for parents on prominent short video platforms like Bilibili and TikTok, where accurate data is crucial for early intervention. Methods We conducted a cross-sectional study, analyzing 125 eligible DDH-related short videos from Bilibili and TikTok. Video characteristics, author types, and interaction metrics were extracted. Content quality was assessed by medical professionals using the modified DISCERN (mDISCERN) and Global Quality Score (GQS) tools. Ordinal logistic regression identified factors influencing quality. Results Significant inter-platform differences were found in video characteristics and engagement. While both platforms showed generally high quality, Bilibili slightly outperformed TikTok. Author professionalism (GQS OR=4.025; mDISCERN OR=5.585) and video duration (GQS OR=1.010; mDISCERN OR=1.010) were significant positive predictors of quality. Critically, a negative correlation existed between higher interaction metrics (likes, comments, shares, views) and perceived video quality. Conclusion While short video platforms significantly impact DDH health information, quality varies, with author professionalism and video duration predicting higher standards, yet popular videos often lack scientific rigor, highlighting an urgent need for enhanced quality control and expert-driven content.
